How are people still using toilet papers in developed countries? It still amazes me. I am from a developing country and it costs around $15 to fix a new bidet/handheld-shower to my existing pipe connection. There is the cost of water though. But then again. I am in a rainy area. Water crisis might never occur here. Plus all the waste is going to ground. So, not much to worry here. But seriously. Use bidets or at least handheld-showers
